We've been using the beta version in a medium-scale e-commerce system and could not be happier! Since the declarations are so simple to write, we've managed to reduce our front-end design costs by over 75% by hiring people who are not capable of abstract reasoning.<p>As you are all probably aware, abstract reasoning only develops after age four. Children under four also happen to be a major liability for families in developing nations. We have effectively killed two birds with one stone by putting unproductive toddlers to work. They pay for their own diapers, we get cheap frontend developers - everybody wins!
